Beit known that \ve,lE LnfR ED and OTIS WELLS, citizens of the United i:and Stokers; and we States, residing vatNormal. and Bloomington, inthecounty of MoLea'iiand-State ofl Illinois,have invented certain new andusevtul. Improvements in Combined lCrushers 'and exact descriptioning-to be a full, clear,

Thisinvention relates to stolcers, and more specifically to an improvedcombined. (5o-ati? cru'sher .and Stoker. One obj-ect of the invention isto provide an improveddevice of thischaracter which sive preliminarylchanges to the `lo cont )tives lire-box :and tender.

The con 1 veyer member 6 is preferablyof the worni4 type, h`aving.a helical plate 1.1 extend-ing ap-4proximately from. endftoaend. rI`he hopper 4 isin eectlaJ continuationof .the conveyer` .tube-3, and; the c rusher member 57is formed or.secured in rigid relation with the hopper' and conveyer' tube.. Byreferring to Fig. 3

nfconnection with Fig; l, it will be seen that the cri'ishe-r `member .5includes an arcuate series 'of bars or ribs 12 whichy converge from`front to rearand arealSo inA convergent-relation to the axisof therotaryy conveyer member'v 6. The conveyer member extendsv from theconveyer tube 3 under the Crusher member'finto'the hopper 4, andtherefore,

wlenthe member '6 is rotated in the proper direction while coal lis inthe'hopper 4, Such" coal will be fedy from the hopper into the tubeandthrough the flatter into thespo'ut" -9`. -The coal, inpassing from thelhozp'per to.

the conveyer tube, is guidedinto the latter by the .convergingarrangement 4of bars or ribs 1'2,` and the large-lumps are crushedby.thefcorrelated or combined actionoffthe conveyer member 'lia'nd the:rushing'l device 5.

Theseconduits may be of any appropriate construction, but preferably consistrespectively of a plurality of frustoconical-tube sections which aremovably connected to one another in such relation that the conduit maybe flexed laterally in all directions, and may be lengthened.and'short-l ened to a limited extent. In the'present embodiment of theinvention, two 'of the' flexible conduits 14 are disclosed, their upperends being united through the medium of a Y-connection 13"L which formsan element /of the member 13. The deflector blade 15 is pivotallymounted at 16 at the lower portion of the member 13,'and a lever orcrank 17 is provided `for turning the member 15 'either rightward orleftward so as to prei vent the low of coal through either electedsecured thereto by any'appropriate means.

It will be seen, therefore, that the elements 3 to 9 inclusive aresupported independently of the fire-boX,-and that the elements 13 to 21inclusive arer supported independently of the tender or coal-hin, andthereforefany tender provided( with a conveyer of this character may bequickly and easily con-- nected in stoking vrelation to any fire-bozeequipped with a feed nozzle 20 and the ele-'- ments supported thereby.It will be seen,

moreover, that a device of this charactermay bevery vquickly andeasilyattached to a locomotive of any ordinary type with comparativeease and facility and without changing the 'fire-box and 'cylinder toany considerable extent.

yIn orderthat the coal shall not clog or accumulate inthe nozzle 20,steam-'jets or.

' nozzles 22may be provided, so that a blast of steam may'not onlydislodge f the coal from the nozzle 2Q 'and carry this coall into thelire-box,'but will alsoaid combustion in a manner which is known tothose who are familiar with the art. A -door 23 may be provided at therear end of the nozzle, so

' that a poker or other implement may be employed for dislodging coalwhich cannot be dislodged by the steam-jet 22.

Attention is directed to the fact vthat the p ipe and its dischargespout 9, are carried' rigidly by the tender, and the pipes 14 and theY-coupling 13a are lcarried totally-by the locomotive, being detachablyconnected with said spout by means of the bayonet slots. 13b and ytherollers 9a. These parts not only afyfordl a `detachable connectlonbetween the two' 'units of the Stoker, but they afford a swivelconnection between them which comes into play when relative turning ofthe locomotive and tender takes place.- When the tender andlocomotiveare to be uncoupled,

this combined swivel and detachableiconnection is disengaged and theseveral sections 0f the pipes 14 then nest snugly 'vv/ith-4 in eachvother into a compact formation which occupies but little space.

Although we have described this embodiment of our invention veryspecifically, it is not intended t0 limit this invention to these exactdetails of construction and arrangement, but changes may-be made withinthe scopeof th'e inventive ideas as implied and claimed. 1

. What we claim as our invention is:

1. The'combination with a locomotive and its tender, of a forwardlyinclined coal conveying pipe carried rigidly by the tender and providedat its front end' with adepending discharge spout, an inverted Y-coupling having a combined. detachable and swivel connection with saidspout, and a pair 'of fuel feed pipes connected at their I upper endswith'the branches of said Y v coupling and carrying said coupling, saidfuel'vfeed pipes being carried .by theylocov motive, divergingdownwardly to the firebox thereof, and being formed of loosely connectedinterttmg sections designed to nest within each other when saidY-couplingis detached froml said. discharge. 'spout to permit uncouplingof tender. v i v 2. A structure as specified in claim l, said combineddetachableI and swivel connection consisting of bayonet slots insaidY-coupling having horizontally elongated inner ends, land rollers onsaid discharge spout received in said slots. and aI apted to travel:

l the locomotive and along said horizontally elongated ends thereof whenthe locomotive and tender turn relatively.

In testimony 'whereof we. have hereunto set our hands. v
